i invention relates to fountain pens, and

one object is to providea novel and inexpen- 5 provide a construction whereby the sive construction permitting ready assembly of the necessary, pen. points therewith and renewal of thesame in a simple and efiicient manner and without disturbing the feed bar or the ink-supplyin g means.

A further object of my invention is to provide a construction that will permit the use of pens ofanyordinary type and material,

. including those made of stainless steel and/or erence'being had to the accompanying drawin s: in which:

Itis the common practice, in the construction-of fountain pens,.to assemble the-pen element in: permanent position with respect to the feed-bar, and then to mount the com .binedpenand-feedbarin permanent relation FOUNTAIN? PEN l y 1931. serial No. 550,353.

to gthe barrel; of the fountain pen. The pens if i so mounted are usually of gold, and any change required by reason of damage or otherwise, required expert work in the factory;

. In the construction of thepresent fountain pen structure, I propose to use ordinary pens made of any material; any suitable metal,

stainlesssteel and or the like, and thefeature the fingers with ink, and with the assurance that the structure'will operate perfectly. as soon as a fresh pen is positioned.- Such positioning is entirely automatic andwhenthe retaining member is in place 'thepen is ready for use.- The construction also permits ready cleansing ofthe ink roove of the feed-bar,

should occasion-require. It will be understood of course that the usual gold pens may be employed, if. desired.

In'the drawings, 1 represents the shell or barrel of the fountain pen which may be of i sleeve member 2, considering the position of the parts as illustrated in Figs. 1 and 2,

'is cut away as indicated at2, exposing a portion of the feed bar 4, and this exposed portion of the feed bar, which may have a substantially semi circular contour 0r. sursired, Without effort and Without staining 7- ployed is provided with an engaging p01 tion which may be in the form of a boss or projection 6 struck up from the body of the same, as clearly illustrated in the drawin s, and the pen is retained in place and proper y positioned with respect to .the feed bar by means of a hollow cap member 7, threaded onto the end of the sleeve member 2; such cap member fully enclosing and covering the cut away portion of the sleeve member. The hollow cap member is internally shouldered at 7, and when it is finally seated in position, this internal shoulder engages andpart- 1y rides on the engaging portion ofQthe pen, which may be the projection 6, and forces the latter rearwardly; amming it incontact with the wall 2* of the sleeve'member 2, and closing the ink groove 4: of the feed-bar 4. Additionally, this engagement of the cap member 7 presses the pen into close contact with the feed-bar over said ink groove 4" and prevents an leaka e of ink. The ca member is readily removable for the insertion of a fresh pen of any suitable type, but with a properly shaped shank, which may be positioned in the manner indicated at any time by the u'serof the pen.

While the end of the pen shank is shown as rounded in Fig. 2, it may be slightly flattened indicated at 5, Fig. 5, for engagement with the shoulder or wall 2 of the sleeve member 2, so as to further insure the sealing of the ink groove of the feed-bar.

In lieu of this arrangement, the sleeve memher 2 may be slightly recessed, as indicated at 2, Figs. 6 and 7, so as to permit the end of the pen shankto fit into the same.

It will be understood, of course, that pens of any type, having shanks of the proper size and contour fitting the feed-bar may be em? ployed in any of the constructions illustrated, and that the shanks of such pens will have a contour or shape exactly fitting the surface of the feed-bar; thereby insuring closure of the ink groove.

In the broader aspect of my invention, which comprises an improved construction permitting ready separation of certain parts of the fountain pen structure to replace a pen, 'it is not necessarythat the feed-bar be of a construction requiring the pen to cover the ink groovethereof, and in Fig. 8, I have shown a feed-bar 40 having a bored or drilled ink passage 40 In the connection with this arrangement I have shown a relatively deep recess a0" at the end of the ink passage directly underlying the opening usually provided in pens; insuring proper feed of ink. This recess or reservoir may also be emplo ed with the type of feed-bars shown in the oter views.

I do not wish to be limited to the use of a boss such as indicated at 6, as the part engaged by the cap member 7 and in Fig. 9 I have shown a pen 50 having a transverse rib or projection 60, which may be engaged by the internal shoulder 7 of the cap member 7. As a further modification I may employ a plurality of bosses, as indicated at 60 Fig. 1

\Vhile I prefer to use pens having relatively straight shanks as illustrated in Figs. 2, 3, et seq., I may use pens having tapered shanks; a construction familiarly found in :gold pens, and in Fig. 10 I have shown a pen 51 of this type, having a single boss or projection 61 It will be understood of course that pens having these tapered shanks may be provided with atransverse rib, such as shown in Fig. 9, or the plurality of bosses shown in Fig. 11.

In general a pen with a shank of semi circular contour is preferable, but I do not wish to be limited to such construction and other forms are illustrated in Figs. 12 and 18. In Fig. 12, I have shown a feed-bar slightly flattened as at 4 and the en shank has a flattened portion constructed to closely fit the same. In Fig. 13 the pen shank is shown as provided with a rounded rib on its underside, which rib is aligned with the ink groove 45 and additionally serves to make close contact with the feed bar and seal such V groove.

The inner wall of the sleeve member 2 engages the pen shank and insures its assumption of the right position with respect to the feed-bar, and also prevents the pen moving out of position with respect to the feed-bar.

A fountain pen comprising a barrel having ink supplying means, a tubular sleeve therefor, a feed-bar permanently associated with said tubular sleeve; the latter being part1 cut away to expose a portion of the feedar, a pen arranged to overlie the feedbar and extend over the portion exposed by the tubular sleeve, and a cap in threaded engagement with said sleeve adapted to overlie said pen and secure the same in place.

2. In a structure such as set forth in claim 1, a pen having a portion engaged by the cap whereby end thrust may be imparted to said pen.

5. A fountain pen comprising a barrel, a tubular sleeve therefor carrying ink supplying means, a feed-bar with an open ink groove permanently associated with said tubular sleeve; the latter having a threaded extension and being partly cut away to expose a portion of the feed bar, a pen removably arranged to overlie, the ink groove of the feed-bar, and a detachable cap adapted to overlie said pen and secure the same in place and'seal said ink groove. 1 a

6.

pen arranged to overlie the feed-bar and within the portion exposed by the tubular sleeve; said ink groove being sealed by said pen, and a cap adapted to overliesaid pen and secure the same in place and cooperatmg to hold the pen in tight engagement with the feed-bar over the inkgroove thereof.

7. In a structure such as set forth in claim 6, a pen having a portion engaged 'by the cap whereby endwise and downward thrust may i be imparted to said pen.

' 8. In a structuresuch as set forth in claim 6, a pen having an integral struck-u projecting portion engaged by the cap w ereby endwise and downward thrust may be imparted to said pen,

9. In a structure such as setforth in claim 6, a tubular sleeve having a recess receiving the end of the pen shank.

10. In a structure such as set forth in claim 6, a feed-bar having a flattened surface adjacent the ink groove, and a pen having a shank conformingfto said flattened surface.

11. In a structuresuch as set forth in claim 6, a pen having a shank with a longitudinal rib on itsunder surface alignedvwith and engaging the edges only of the ink groove.
